Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100198, here are decompositions:

  • 5 + 100193 = 100198
  • 29 + 100169 = 100198
  • 47 + 100151 = 100198
  • 89 + 100109 = 100198
  • 149 + 100049 = 100198
  • 179 + 100019 = 100198
  • 227 + 99971 = 100198
  • 269 + 99929 = 100198

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,198 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 100198 first appears in π at position 403,873 of the decimal expansion (the 403,873ordinal-suffix:rd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
